Methods of testing disk packs on an amplitude detection principle are widely used at present for initial testing, but the detection methods used in computer systems are based on a time detection principle which is less sensitive to changes of amplitude.This paper outlines the usefulness of amplitude detection as a method for testing disk packs and compares it against a technique based on time detection.

Inspec keywords: magnetic disc storage

Other keywords: magnetic disc storage; disc pack testing; amplitude detection principle

Subjects: Storage on moving magnetic media
